Hey there faced with the following problem:
I have two hardware setups:
1. Laird DEVK-654 (nrf52480) without external oscillator
2. Laird BL654 mounted to a carrier board with a Raspberry Pi cm3, connected to usb lines, with external oscillator, schematic verified by laird
Testsystem is on kernel 4.14 (crypto user api enabled) ; Bluez 5.48; zephyr is zephyr master & zephyr 1.13.0
zephyr is being compiled with RC enabled for 1 and xtal enabled for 2
on zephyr master 1. & 2. are recognized as usb devices but timeout during initialization by bluez bluetoothd:
https://github.com/zephyrproject-rtos/zephyr/issues/10678
on zephyr 1.13.0 (1.) is being recognized as usb device and initializes successfully, (2.) is not recognized as usb device at all
Any idea where to start looking for the problem?
Best,
Matthias
